[Paraview] exporting selection labels to an SVG as editable/movable text-objects

[Dr. Roman Grothausmann]

I just noticed that the problem only occurs if a $ (as needed for latex math) is 
used in the format string, e.g. $%.2f^\circ$. If I remove the $ signs the text 
IS exported with text-tags.
Does the $ sign have a special meaning here in PV?
